if the car is tuned up propper AFRs should be like any other NA car. at WOT from 2000 to 4000 rpm at around 13to 14.And over 4000 RPM u should see 12 12 + AFR. what u need to do my friend is get a boost gauge, a wide band and install the turbo kit. set the boost and try and setup the cis to flow more. i think u have some sort of mechanical controller on the side of the Fuel dizy that can be adjusted.
